Why Powerwall

Powerwall is a rechargeable home battery system designed to maximize your home's energy independence. That means seamless backup and a smaller carbon footprint for your home, and potentially savings on your electricity bill. Powerwall is an intelligent system that can be customized to your energy needs, with the ability to charge from solar so energy is always available on demand.

With Powerwall 3, supply more power with a single Powerwall unit to meet your present or future needs for your home. Learn more about what to expect with Powerwall 3

Seamless Backup

When the grid goes down, solar energy will continue to power your home and charge your Powerwall. With Storm Watch enabled, Powerwall can communicate to the National Weather Service and prioritize charging in anticipation of severe weather. In the event of Powerwall changing status due to severe weather, you will receive a push notification from the Tesla app.

Self-Powered Home

At night, Powerwall can provide your home with clean energy that you've generated from solar during the day.

Time-Based Control

If your utility offers Time-of-Use rates, you can use less expensive solar energy you've already generated to avoid electrical charges during more expensive rate periods.


Each Powerwall installation includes a complete energy monitoring solution for your home. You can see how your home both produces and uses energy at any given time.


What to Expect for Powerwall 3

Powerwall stores your solar energy for backup protection, so when the grid goes down your power stays on. Powerwall home battery continues Tesla’s mission and makes clean energy accessible to all, day and night.

For most homes, you can receive whole-home backup to power your entire home during an outage and have energy independence by producing energy with solar. You can also reduce your reliance on the grid and save money on utility bills. Once installed, Powerwall can be monitored and managed using the Tesla app to customize system behavior to meet your energy goals.

Powerwall 3 is a fully integrated solar and battery system, designed to meet the needs of your home. Powerwall 3 can supply more power with a single unit and is designed for easy expansion to meet your present or future needs. Powerwall 3 features an integrated solar inverter allowing solar to be connected directly for high efficiency; it can also be added to existing solar or installed on its own, like Powerwall 2.

Powerwall 3 is now available thru TIER 1 Solar Solutions in the following states:

 Arizona                                               Illinois                                                  Pennsylvania

Powerwall Works

Powerwall gives you the ability to store energy for later use and works with solar to provide key energy security and financial benefits. Each Powerwall system is equipped with energy monitoring, metering and smart controls for owner customization using the Tesla app. The system learns and adapts to your energy use over time and receives over-the-air updates to add new features and enhance existing ones.

Models of Powerwalls

Powerwall is a rechargeable home battery system that can be installed with solar.

Powerwall 3 and Powerwall+ are designed for owners installing a new solar and storage system. Solar systems are integrated directly into the Powerwall, for higher efficiency and more compact installation with solar inverters being included. Powerwall 2  is designed to be added on to existing solar systems and is compatible with all major inverter brands.

Models of Powerwalls

‡Flood resistant to over 2 ft

With Solar

When the sun rises, solar begins powering the home. When additional power is required for the home, the home can pull it from the utility grid.

Powerwall is charged by solar during the day, when solar panels are producing more electricity than the home is consuming. Powerwall then stores that energy until the home needs it, such as when solar is no longer producing at night, or when the utility grid is offline during a power outage. With Tesla, when your Powerwall system changes status, such as the utility grid going down or offline, you can expect to receive notifications from the Tesla app.

When the sun comes out the next day, solar recharges Powerwall so you have a cycle of clean, renewable energy.

Without Solar

If your electricity rates vary throughout the day, Powerwall can charge when your utility’s electricity costs are low and discharge when electricity costs are high, generating automatic savings. Powerwall will also provide seamless backup power by detecting grid outages and automatically becoming the home's main power source.

Without Backup

When Powerwall+ is installed by itself with a non-backup configuration, it fully operates when the grid is active but does not provide power when there is a grid outage. Owners can use the power they generate with solar at night, export energy at peak prices and participate in Virtual Power Plant programs.

Note: Non-backup is not currently supported for Powerwall 2 and Powerwall 3.

Future Backup Upgrades

A non-backup system can be upgraded to include backup features later using Backup Switch. Reach out to your installer about the outlook for upgrading to a backup system. 

Note: Californian utilities are expected to approve Backup Switch for residential homes by 2024. 


What Can Powerwall Back Up

Tesla-Powerwall-backup-example-house -at-night-time-with-powerwall-powering-the-lights

Powerwall is designed to store solar generation for use at night and protect against power outages. How much your Powerwall can back up and for how long is dependent on multiple factors such as the number of Powerwalls and appliances you have and your home’s energy usage.

Depending on the number of Powerwalls and type of backup protection, what your Powerwall can back up includes 120 V loads such as lights, plugs and small appliances as well as 240 V heavy loads such as air conditioners, electric cooking ranges, well pumps, EV charging, electric dryers, electric water heaters and pool pumps.

Types of Backup Protection

The energy needs of your home and the number of Powerwalls determine whether whole home backup or partial home backup is provided.

Whole Home Backup

With whole home backup, your Powerwall will be able to support your entire home including all appliances during a power outage.

Partial Home Backup

Partial home backup allows you to choose the essential loads to back up, such as lights and outlets, and leave out heavier loads, such as air conditioners and washing machines. When the grid is operational, you will be able to use and monitor all appliances. When the grid is down, only the loads you deem essential will be usable.

Next Steps in Sizing Your System

You can get a general indication of how many Powerwalls may be suitable for your home on our website. To see how many Powerwalls you will need to back up your home during a power outage, design your Powerwall, select ‘View Backup Guide’ and enter your electric bill. Select your Powerwall model to determine what your Powerwall can back up.

However, there are many variables such as climate, home orientation and energy use goals, that make each home unique. For a final detailed recommendation on system design, talk to your Tesla Advisor or a Tesla Certified Installer.

Appliances Compatible for Back Up

Your Powerwall can back up most appliances including:

  • Standard appliances such as refrigerators, lights, Wi-Fi routers, televisions and microwaves

  • Energy intensive appliances such as dishwashers and air conditioners
